Pindac, I know nothing about your phono stage and certainly never said or even implied that it was inferior. Originally, I was merely asking about how the term "Transconduction" might apply to the mystery phono stage that you like. The way you used the term, it seemed you were suggesting it is a category of phono stage opposite to a "Transimpedance" or current driven phono stage. To me, the alternative to current drive is voltage drive, and there is no need to adopt the term transconductance because in fact all audio gain devices act through transconduction. Then you revealed finally that your phono stage at least starts life as a Paradise phono, made on a custom basis in the UK, so far as I can tell. I read something about it and commented that it received a lot of favorable mention on the internet, and that it appears to use an FET and a tube complement that are both reminiscent of the Herron phono stage that is much liked on this side of the pond. Please show me where I criticized the Paradise phono, on any basis at all, let alone its relatively low cost. I also never in any way said that cost is directly proportional to results in audio. It most certainly is not.
SUT help
Hello all,
I've combed the forums and pretty much every SUT thread either devolves into arguments of the merits for/against, or gets hyper specific. I'm assuming to properly match a SUT, it needs to be selected based on the cartridge AND phono pre-amp. Since I haven't found a thread about my specific combo...here I am.
I don't know a TON about SUTs, but I'd like to experiment to see if adding one will enhance my experience.
Currently, my cartridge is a Hana ML and my phono pre-amp is the Modwright PH 9.0XT. I may possibly move up to the Hana Umami Red in the nearish future, but the specs are fairly similar between that and the ML.
Hana ML specs: 0.4mv; 7 ohm/1khz
Hana Umami Red specs: 0.4mv; 6 ohm/1khz
Modwright PH 9.0xt - MM input is 52db gain, with option to lower -6 and -12 to 46db and 40db.
I currently use the MC input which offers 64db of gain (-6, -12). I've typically kept it at 64db and alternate between 100ohm and 250ohm for load impedance settings. The 470 is too much.

Not sure if its possible to have a SUT that would work well with both the ML and umami red, but if so, I'm all ears. If not and they each need specific ones, I'd be considering the ML first and foremost.
Any help is appreciated. I don't really have any clue how to determine what ratio is best and whether copper or silver pair better with these cartridges. I had EM/IA recommended to me in the past, but their pricing is well beyond what I'd like to spend on one (~$1500 or less, ideally?)

@bobsdevices , I have an Hana ML. which one of your products do you recommend? Even older models would be fine. I also have the Mod Wright 9.0. |
@lewm I do not own a Paradise at the present or any other time. I have described how I have experienced the Paradise as a SS Circuit as a few build guises. I also made it known that an alternative SS Phon' is also known to me that is one I am very impressed by. I am without a Vinyl Source, it is packed away ready for storage. I have a few intersting experiences to be had around Vinyl Replays in the future. I am having most of the Musical experiences in the homes of others. For myself, being social around my hobby is more important than the music replays and much much more important than equipment. |
@mmcgill829 We have used SUTs in our preamps (I prefer direct FWIW) but one thing we noticed was the less gain you try to get from the SUT the better. So if it does have reconfigurable stepup (like the Jensen JT-346, which is an excellent SUT, one of the best), use the least amount that will get you enough gain. Its Ok if you have to run the volume up on your line stage a bit; as long as the noise floor of the phono section overall is less than that of the silent grooves of a good quality LP, you're good to go. IOW 1:10 is better than 1:20. |
